Several files are converted in parallel worker threads, with per-file progress and cancel.

About Convert to GIF
About GIF
GIF is the classic animated image format. It is limited to 256 colours per frame and 1-bit transparency, so photos look grainy and files are large, but it plays everywhere.
A GIF starts with 'GIF89a' (or the older 87a), a logical screen descriptor and an optional global colour table, then image blocks, each preceded by a graphic control extension that sets its delay and transparent colour.
Strengths: Animation that works everywhere; Simple, universally supported; Good for small flat graphics.
Drawbacks: Only 256 colours per frame; Hard-edged transparency only; Large files for photos or long clips.

Frequently asked questions
Which apps open GIF files?
Every browser, operating system, chat app and editor.
Which formats can I convert from?
Anything this site can read: JPG, PNG, WebP, AVIF, HEIC, GIF, SVG, TIFF, BMP, ICO, JPEG XL, PSD, RAW and more. Files are identified by their bytes, so a mislabelled file still converts.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
